From one of the topics in that Aus/NZ Offficial Playstation Forums i linked to in my previous post.

According to one of the posts there (can't find it again) it suggests...
Yes, you can put a 7200rpm Hdd in there "but also according to this thread/post" Sony dose not recommend it due to the possibility of causing heat issues due to the faster rotation speeds.

although i don't know much about this stuff, i thought "i" would mention this just in case it is true.
